Sunscreen is an essential part of your daily skincare routine, protecting your skin from harmful UV rays that can lead to premature aging, sunburn, and even skin cancer. But like all things, there’s a right and wrong way to use sunscreen. Whether you’re hitting the beach or just going about your daily life, following these do’s and don’ts will help ensure you’re getting the most out of your sunscreen and keeping your skin safe.
The Do’s of Sunscreen
- Do Apply Enough Sunscreen
One of the biggest mistakes people make is not using enough sunscreen. For proper coverage, adults should apply about one ounce (enough to fill a shot glass) to cover their entire body. If you’re just applying to your face, use about a nickel-sized amount.
- Do Reapply Regularly
Sunscreen wears off after a while, especially if you’re swimming, sweating, or spending extended periods outdoors. Reapply sunscreen every two hours, and immediately after swimming or excessive sweating.
- Do Use Sunscreen Every Day
Sunscreen isn’t just for sunny days at the beach. UV rays can penetrate through clouds and even glass, which means you should be wearing sunscreen daily, even on cloudy days or if you’re spending most of your day indoors near windows.
- Do Choose Broad-Spectrum Sunscreen
Make sure your sunscreen offers broad-spectrum protection. This means it will protect your skin from both UVA and UVB rays. UVA rays can prematurely age your skin, causing wrinkles and age spots, while UVB rays are responsible for sunburn. Both types can lead to skin cancer.
- Do Use a High SPF
The American Academy of Dermatology recommends using a sunscreen with at least SPF 30. SPF 30 blocks 97% of the sun’s UVB rays. Higher SPFs block slightly more UVB rays, but no sunscreen can block 100% of UV rays.
- Do Apply 15 Minutes Before Going Outside
For optimal protection, apply your sunscreen at least 15 minutes before you go outside. This allows the sunscreen to bind properly to your skin and provide the protection you need when you step out.
- Do Use Water-Resistant Sunscreen
If you’re swimming or sweating, opt for a water-resistant sunscreen. This doesn’t mean it’s waterproof, so you’ll still need to reapply after water activities, but it will provide better protection for longer in wet conditions.
The Don’ts of Sunscreen
- Don’t Forget to Cover All Exposed Areas
It’s easy to miss spots like the ears, back of the neck, tops of the feet, and even the scalp. These areas are just as susceptible to sun damage and need protection too. Make sure to cover all exposed skin to avoid painful burns or long-term damage.
- Don’t Rely Solely on Sunscreen for Sun Protection
While sunscreen is an important part of your sun protection strategy, it shouldn’t be your only line of defense. Seek shade whenever possible, wear protective clothing, hats, and sunglasses, and avoid the sun during peak hours (10 a.m. to 4 p.m.).
- Don’t Use Expired Sunscreen
Like many skincare products, sunscreen has an expiration date. Using expired sunscreen means you’re not getting the full protective benefits, which can leave you vulnerable to sun damage. Check the expiration date on your sunscreen, and if in doubt, toss it and buy a new bottle.
- Don’t Assume Dark Skin Doesn’t Need Sunscreen
People with darker skin tones may be less likely to burn, but they are still at risk for sun damage and skin cancer. Everyone, regardless of skin tone, should wear sunscreen regularly.
- Don’t Neglect Lip Protection
Your lips can burn too! Use a lip balm with SPF to protect your lips from sun damage. Regular lip balms won’t provide adequate protection, so make sure it’s labeled with SPF 15 or higher.
- Don’t Expect Immediate Protection
As mentioned earlier, sunscreen needs time to activate. Applying it right before you go out into the sun means you’ll be unprotected for the first 15 minutes. Always give your sunscreen time to set before heading outdoors.
Comprehensive Q&A Section
Q: How much sunscreen should I apply to my face and body?
A: For your face, use about a nickel-sized amount of sunscreen. For your entire body, adults should apply approximately one ounce, which is about the size of a shot glass. Ensure all exposed areas are covered.
Q: Can I use the same sunscreen on my face and body?
A: Yes, you can use the same sunscreen on your face and body. However, some people prefer to use a facial sunscreen that is formulated to be lighter and less greasy, especially if they have sensitive or acne-prone skin.
Q: How often should I reapply sunscreen?
A: You should reapply sunscreen every two hours when outdoors, and immediately after swimming or sweating. Even if you’re not swimming or sweating, sunscreen can wear off over time, so regular reapplication is key.
Q: What does “broad-spectrum” mean on sunscreen labels?
A: Broad-spectrum sunscreen protects against both UVA and UVB rays. UVA rays can cause premature aging and contribute to skin cancer, while UVB rays are responsible for sunburns and also contribute to skin cancer.
Q: Does SPF 50 provide significantly better protection than SPF 30?
A: SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks about 98%. While SPF 50 offers slightly better protection, no sunscreen can block 100% of UV rays. The difference between SPF 30 and SPF 50 is minimal, so both are excellent options.
Q: Can I wear makeup over my sunscreen?
A: Yes, you can wear makeup over your sunscreen. Apply your sunscreen first, allow it to absorb fully, and then apply your makeup as usual. Some makeup products also contain SPF, but they should be used in addition to, not as a replacement for, sunscreen.
Q: Should I use sunscreen if I have oily or acne-prone skin?
A: Yes, people with oily or acne-prone skin should still use sunscreen. Look for oil-free, non-comedogenic formulas that won’t clog pores or contribute to breakouts. Many sunscreens are designed specifically for oily skin and offer a matte finish.
Q: Can babies and toddlers use regular sunscreen?
A: Babies under six months should not use sunscreen and should be kept out of direct sunlight. For older babies and toddlers, use a sunscreen that is formulated for sensitive skin, ideally one that contains physical blockers like zinc oxide or titanium dioxide.

By following these do’s and don’ts, you’ll be better equipped to protect your skin from the harmful effects of the sun. Remember, sunscreen is not just for summer; it’s a year-round necessity to keep your skin healthy and youthful. Protect yourself today for a brighter tomorrow!
